Margin calls are a fundamental part of leveraged trading, especially when it comes to short positions. Margin itself is the collateral traders must post with their broker when opening trades with leverage. The main idea behind leverage is straightforward: it lets traders control positions many times larger than their actual capital, amplifying both gains and losses. However, if a position moves against a trader, and account equity falls below a certain maintenance threshold, the broker issues a margin call. This requires the trader to either deposit more funds or liquidate positions to reduce risk.Short positions, which profit when an asset's price falls, are especially exposed to margin call risk. When you short an asset, you borrow it to sell at the current price, hoping to buy it back later at a lower price. If the price climbs instead, potential losses are theoretically unlimited since there’s no cap on how high an asset can rise. In these situations, margin requirements can quickly balloon, and the combination of unfavorable price movement with increased volatility can force traders into liquidating their positions at a loss.An illustrative scenario can be found in example cases where traders sell put options as part of an options strategy. Selling puts is akin to taking on a short position, betting the underlying asset will not fall below a specified level. Under routine market conditions, this can generate modest, consistent income. The problem arises when markets turn sharply downward. Not only does the asset price fall, but implied volatility often rises dramatically, both of which increase the value of the put option. Since margin requirements are typically five to ten times the premium received, even a modest increase in option value can chew through available margin at an alarming rate. In a real example highlighted by Moomoo, a trader who sold a put saw its premium triple during a steep decline, triggering a margin call and, unless funds were added, forced liquidation at an unfavorable price.This kind of risk is called tail risk—the chance of a rare but extreme event that generates enormous losses. The “high probability, small profit” profile of short put positions flips, exposing the trader to “low probability, massive loss” risks. The October 2025 Bitcoin market is another clear example, as reported by AInvest. During that period, an overwhelming bias toward short positions in perpetual futures created a fragile equilibrium. Massive, rapid liquidations of short positions occurred when prices rebounded, with over $17 billion in liquidations in a single event. Leverage played a crucial role here: as prices moved up against shorts, margin requirements shot up, triggering cascading margin calls and liquidations.Funding rates in futures markets add another dynamic. In periods where futures trade above spot prices—known as contango—shorts often receive funding payments from longs. But if the market reverses or prices stabilize, those payment advantages can evaporate just as losses mount. The complexity of these mechanics means that even well-placed short positions can find themselves in trouble quickly if volatility spikes, funding fee conditions change, or a strong rebound occurs.For anyone attempting these strategies, risk management is absolutely critical. Tools such as strict stop-loss rules or rolling positions—closing the current trade and reopening a similar one with more favorable parameters—can help reduce tail risk, but they aren’t perfect. If the underlying asset’s fundamentals deteriorate or market conditions worsen dramatically, rolling positions may only increase cumulative losses.Leverage is a double-edged sword, amplifying both opportunity and danger. Ignoring key concepts like margin thresholds and free margin leaves traders exposed to a higher risk of margin calls, especially when prices move rapidly against them. These risks are amplified in high-volatility market environments or in assets that are subject to sudden news or policy shocks, like cryptocurrencies or commodities.Thanks for tuning in and don’t forget to subscribe.
